What Materials Does GNEE RAIL Use To Manufacture Railway Elastic Clips

Aug 19, 2025 Leave a message

Rail elastic clip is one of the popular fastening parts to keep rail track fixed on rail sleepers(wooden sleeper and concrete sleeper). Rail clamps are also used in some rail fastening systems.

 

GNEE RAIL supplies elastic rail clips with high precision, high tensile strength and corrosion resistance, such as skl/kpo/nabla/fast/fist/e type rail clip, etc.,which are used widely in railway projects all over the world.

GNEE RAIL commonly uses high-quality spring steel in the manufacturing of rail clips. Spring steel is primarily applied in the production of springs and other elastic components in automotive and industrial suspension systems. These steels are typically low-alloy manganese steels, medium-carbon steels, or high-carbon steels, characterized by exceptionally high yield strength.

 

In addition, spring steel offers excellent comprehensive properties, such as mechanical performance, ballistic resistance, fatigue resistance, hardenability, as well as outstanding physical and chemical properties. The raw materials we use for rail clip production mainly include spring steel grades such as 55Si7, 60Si7, 65Si7, 55SiCr7, 60Si2MnA, 60Si2CrA, 55Si2Mn, and 38Si7.
